Trade effluent forms and guidance

Whether you’re a large multi-site business or a Small Medium Enterprise (SME), it’s really important that you understand if you need consent to discharge trade effluent.

To help make sure the environment, public health, sewer network and treatment works are protected, it’s a legal requirement that businesses have permission to dispose of trade effluent – it could lead to legal action and cause harm to the environment if you’re not doing this properly. To regulate trade effluent, businesses are provided with discharge consent.

What is trade effluent?

Trade effluent is any liquid waste that’s discharged into the sewers from a process or activity carried out by a business. This is different to your usual kitchen and bathroom waste (domestic sewage).
